I don't have mine set up to sign them all. I did a couple to see if it |
23 |
worked or not. Whenever I sign a message, it asks for the password. It |
24 |
is quite a long password and I don't want to type it in every time I |
25 |
send something. |

The password I was talking about is the one when I send a message. It |
62 |
does ask for the password when Paul was sending a message. Those were |
63 |
off list tho. Anyway, when I put the password in, I can read the email. |
64 |
Otherwise, I can't read anything. |

How sure are we that there is no back door the Government has to bypass |
67 |
this? Are we 99% sure or about 50/50 with our fingers crossed? |
